Specifications

Requirements

• RTD sensors, type PT-100 or PT-1000
• VINT Hub (HUB0001_0)
  • HUB0001_0 replaced the HUB0000_0
• RTD Phidgets (TMP 1200): supports 2-, 3-, 4-wire RTD mode
  The TMP 1200 only allows one RTD sensor per device. You need one TMP1200 per RTD sensor. 
• Phidgets cables (e.g. 3002_0, 3003_0, 3004_0 )

Setup options

Direct connection

• A direct connection applies when adding new probes independently from the roaster's readout. 
• The newly added probe can be connected directly to the Cropster Connector. 

Dual connection

• A dual connection applies when the roaster is equipped with a dual probe. 
• A dual probe is a probe with two sensors inside the hull and two pairs of wires that allow a simultaneous connection to Cropster and the roaster's readout.

VINT Hub + TMP1200 installation

VINT Hub HUB0000 (now HUB0001_0) on the left, connected to a TMP1200 on the right, using a Phidgets cable to perform the connection between the two devices. A 4-wire mode RTD temperature sensor is connected to the TMP1200.

1. Follow the probe cable from the tip of the probe to its end where the wires appear.
   In case of dual probes, take the free end that is not connected to the roaster.
2. Confirm the number of wires available for your PT-100/PT-1000 RTD probe, and follow the next step accordingly:

Two-wire:  To connect a 2-wire RTD to the RTD Phidget, connect one wire to the RTD+ terminal, and the other to the RTD- terminal. Then connect the EXC+ terminal to the RTD+ terminal and the EXC- to the RTD- terminal with two short wires. This is a simple wiring setup for an RTD, but also the least accurate because the resistance of the leads is not taken into account.

Three-wire: Your RTD should have two wires that share a color; connect one of these wires to the RTD terminal and the other to the EXC terminal. The differently colored wire connects to the RTD+ terminal. Then connect the EXC+ terminal to the RTD+ terminal with a short wire. In a three-wire RTD, the extra wire is added to measure the resistance of one of the leads. This calculation assumes that both leads have the same resistance.

Four-wire: To connect a four-wire RTD, simply connect one pair of same-colored wires to the RTD+ and EXC+ terminals, and the other pair to the RTD- and EXC- terminals. A four-wire RTD is normally used in precision measurement, when the assumption that both leads have the same resistance is not accurate enough. Unfortunately, the RTD Phidget does not support this particular feature of four-wire RTDs. It does support the use of four-wire RTDs using the same assumption as the three-wire mode.

3. Connect the TMP1200to the VINT Hub using your Phidgets cable.
4. Repeat the installation steps for each RTD sensor you wish to connect to a TMP1200.
5. Connect the VINT Hub to your computer with the provided USB cable and proceed with the software setup. 

Roasting Intelligence Setup

Installing the Roasting Intelligence software

1. Download Roasting Intelligence.
2. Complete the installation process by following the steps provided.
3. Download the Phidget driver.
4. Double-click the Cropster icon on your desktop to access Roasting Intelligence. 
5. Click the green Login with the browser button.
   

   

6. You will be directed to the C-sar browser.
7. Enter your Username* and Password* and click the green Sign in with password button. 
   Use the same credentials that you use to access the online platform C-sar. 

Establishing a connection to the machine

1. SelectPreferences > Machine > Configuration.
2. To choose the Roast machine, click on the dropdown menu in the Machine section.
3. Click the + Add connector option to choose your connector from the dropdown list.
4. Select Phidgets RTD Sensor (TMP1200) from the dropdown.
5. Click Select to add the connector.
   

   

6. Click on the Gear icon in the Connector setup section to open and configure more settings.
7. Select the following detail:
   • Wiring mode: Select the wiring mode corresponding to the number of leads/wires coming from your PT100/PT1000. 
   • ⚠️ This step is exclusive to the wireless VINT HUB (e.g., HUB5000). Do not perform this action if you are using a standard wired hub or any other hardware model, as it may cause configuration conflicts.
     • Enter the following details:
       • Hostname/IP address: The hostname or IP address of your Wireless VINT Hub.
       • Port: The port of the Phidget Server configured on your Wireless VINT Hub.
8. Click OK.
   

   

9. Navigate to the Machine > Measurements tab. All supported measurements will be displayed.
10. To activate the measurements, simply click the green toggle button. 
11. Enable the desired measurements and choose Phidgets RTD Sensor (TMP1200) as the connector type.(Optional) Click the toggle button to turn on (or off) the Rate of Rise (RoR) curve for your measurements.
12. Select the Hub port: The Hub port refers to the port on the VINT Hub. If the TMP1200 is connected to VINT Hub's port 0, select 0 under Hub port.
13. Select the Type of RTD Temperature Sensors.
    ⚠️  Please check the manufacturer's probe specifications to identify the Type. e.g., An RTD with 100 ohm resistance, and a 3850 ppm/k, corresponds to the PT100_3850 option.
    
    • PT100 or PT1000 = Platinum sensor with 100 or 1000 ohm resistance
    • 3850 or 3920 ppm/K = Temperature coefficient
14. (Optional) Change the order of the measurements by using theDrag and Drop icon and move it into position
15. Click Save to finalize the changes.
    

    

16. Restart Roasting Intelligence. If the setup was successful, you will see the temperature values displayed on the right-hand side of the screen following the restart. 
    

    

Troubleshooting

If Roasting Intelligence indicates No source connected and/or you cannot see any measurements, please verify the following: 

• Is the TMP1200 connected to the VINT Hub? 
• Is the VINT Hub connected to the computer?
• Is the Phidgets driver installed?
• Mac only: has the Phidgets driver been enabled in the Mac's Security & Privacy settings?

If the temperature deviates a few degrees:

• Try the different options for your type of RTD sensor under the Type dropdown menu.
